Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 605,045,419, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 605,045,419 | |
| -1 | -605,045,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,045,419.
Example:
1 x 605,045,419 = 605,045,419
and
-1 x -605,045,419 = 605,045,419
Notice both answers equal 605,045,419
With that explanation out of the way, let's continue. Next, we take the number 605,045,419 and divide it by 2:
605,045,419 ÷ 2 = 302,522,709.5
If the quotient is a whole number, then 2 and 302,522,709.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 605,045,419 | |
| -1 | -605,045,419 |
Now, we try dividing 605,045,419 by 3:
605,045,419 ÷ 3 = 201,681,806.3333
If the quotient is a whole number, then 3 and 201,681,806.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 605,045,419 | |
| -1 | -605,045,419 |
Let's try dividing by 4:
605,045,419 ÷ 4 = 151,261,354.75
If the quotient is a whole number, then 4 and 151,261,354.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 605,045,419 | |
| -1 | 605,045,419 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 337 | 3,707 | 5,729 | 9,601 | 63,019 | 105,611 | 163,217 | 1,795,387 | 3,235,537 | 35,590,907 | 55,004,129 | 605,045,419 |
| -1 | -11 | -17 | -187 | -337 | -3,707 | -5,729 | -9,601 | -63,019 | -105,611 | -163,217 | -1,795,387 | -3,235,537 | -35,590,907 | -55,004,129 | -605,045,419 |
